Potentiometer-controller PO-NTC

Potentiometer speed controler PO-NTC is designed to control fans with EC motors where is required DC control signal. A speed setting can be made through energetic recovery to the input of the fan/controller by connecting the potentiometer to a supply voltage (10V) provided by an EC fan or controller. Controller has a built in temperature sensor NTC 10K.
